From the teachings of Ruben, Neo knew that the older noble ladies always tried to hit subtly on the younger boys.
Although their intention may not be to sleep with them, they sure liked to flirt.
But in the case of Mei Li and Niwa, they were openly giving Neo a ticket to their secret garden.
How so, one might ask?
From Mei Li's slightly seductive tone and the suggestive wink, even a blockhead could deduce her intentions, let alone Neo. As for Niwa, she was even more obvious with her handshake.
No sane woman would say 'I'll come for you' in a conversation with a stranger. Although she didn't show any hints of trying to hit on Neo, this one just gave it away.
Neo was pretty sure that Niwa only hit on him because Mei Li gave her a signal by giggling. If he played his cards right, he could end up in bed with these two sexy cougars before the event was over.
